I think that obtaining verbose boot logs for both cases would be a nice start. If you can't get the log as a text (e.g. via serial console) for the APIC case, then a series of digital camera screenshots would be fine too. P.S. Here seems to be a dmesg of FreeBSD 7 successfully booting on T43 with APIC enabled: http://www.4ucode.com/Study/Topic/1091620 -- Andriy Gapon
